    That's great news. This would certainly strongly indicate that the bad RAM was the issue.

    Crucial has a 100% satisfaction/operational guarantee. If it doesn't work return it.

    But honestly...the replacement you get will very likely be fine.

    Crucial sent me the RAM a few days ago.
    I am actually quite impressed with the return process, everything done very smoothly online.

    I removed the original RAM and put the new RAM it and run memtest.
    They are good.
    I then added the old RAM and run memtest again.
    The result is also good.

    There has been NO incident of the Mac shutting down and restarting since the day I removed the faulty Crucial RAM.
    So the first problem I believe is solved.

    I ran Apple Hardware Test again, the 4MOT/4/40000003-HDD error is still there.
    I am not sure how long the old HDD will last.
    I have also installed Macs fan control and temperature stays between 45-52C with fan speed around 1350 rpm.

    The next project will be have to be HDD replacement...
